Description
Gebiet der ErfindungField of the invention
Die Erfindung betrifft Instrumente, die bei der Präparation des Femurs während einer totalen Kniegelenkrekonstruktion verwendet werden, und betrifft insbesondere das Instrumentarium, das zum Fräsen des Femurs vorgesehen ist, wobei die Möglichkeit gegeben ist, Abschnitte des Femurs unter Verwendung einer einstückigen Schneidführung zu resezieren.The The invention relates to instruments used in the preparation of the femur during a total knee joint reconstruction can be used, and in particular concerns the instrument used to mill the Femurs is provided, with the possibility of sections of the femur using a one-piece cutting guide resect.
Hintergrund der ErfindungBackground of the invention
Bei einer orthopädischen Operation, bei der ein Teil oder das gesamte Gelenk eines Patienten durch ein Protheseimplantat ersetzt wird, wird ein Abschnitt des das Implantat aufnehmenden Knochens präpariert, um genau mit den zugehörigen Flächen des Implantats zusammenzupassen. Wenn das Kniegelenk ersetzt wird, wird das distale Ende des Femurs präpariert, um eine femorale Kniekomponente aufzunehmen, und das proximale Ende des Schienbeins wird präpariert, um eine tibiale Komponente aufzunehmen.at an orthopedic Operation in which a part or the entire joint of a patient through Replacing a prosthetic implant becomes a section of the implant prepared receiving bone, to exactly with the associated Surfaces of the Implant. When the knee joint is replaced, will prepared the distal end of the femur, to accommodate a femoral knee component and the proximal end of the tibia is prepared, to pick up a tibial component.
Bisher wurden diese Oberflächen im wesentlichen unter Verwendung von Schwing- oder Pendelsägeblättern präpariert, die in Verbindung mit einer Serie von Sägeführungen verwendet werden. Die Führungen können lediglich eine Plattform aufweisen, an die der Chirurg das Sägeblatt während der Resektion anlegt, oder können einen Schlitz zum Abfangen des Sägeblattes in diesem aufweisen. Normalerweise wird bei der Präparierung des Femurs eine Serie von Schneidführungen am distalen Femur in einer spezifischen Reihenfolge angeordnet, um Abschnitte des Femurs nacheinander zu resezieren. Diese Schneidführungen werden im allgemeinen vom Chirurgen einzeln in bezug auf spezifische anatomische Merkmale ausgerichtet. Die Verwendung mehrerer Schneidführungen, die eine einzelne Ausrichtung durch den Chirurgen erfordern, kann zu Ungenauigkeiten bei den Schnitten führen, was keinen optimalen Paßsitz zwischen dem Knochen und dem Implantat ermöglichen würde. Solche Sägeblätter, die allgemein bei der Resektion eines Knochens verwendet werden, sind in den US-Patenten 5 002 555, 5 133 728 und 5 135 533 dargestellt. Ein Beispiel für eine typische Schneidführung findet sich in US-Patent 5 053 037, das eine Sägeführung mit eingenommenen Schlitzen darstellt.So far These surfaces became prepared essentially using oscillating or pendulum saw blades, which are used in conjunction with a series of saw guides. The guides can only have a platform to which the surgeon saw the blade while the resection creates or can a slot for catching the saw blade in this exhibit. Usually used in the preparation of the femur a series of cutting guides on the distal femur in a specific order arranged to sections of the femur to resect consecutively. These cutting guides are generally from Surgeons individually with respect to specific anatomical features aligned. The use of multiple cutting guides, which is a single Orientation by the surgeon may require inaccuracies at the cuts, which is not an optimal fit between the bone and the implant. Such saw blades, the are commonly used in the resection of a bone are in U.S. Patents 5,002,555, 5,133,728 and 5,135,533. An example of one typical cutting guide See US Pat. No. 5,053,037, which discloses a saw guide with inserted slots represents.
Die Beständigkeit der Ergebnisse, die erreicht wird, wenn ein Sägeblatt und eine Serie von Schneidführungen verwendet wird, kann stark von Chirurg zu Chirurg variieren. US-5 207 680 zeigt die Merkmale des Oberbegriffs von Anspruch 1.The resistance the results achieved when using a saw blade and a series of cutting guides used can vary greatly from surgeon to surgeon. US 5,207,680 shows the features the preamble of claim 1.
Zusammenfassung der ErfindungSummary of the invention
Das offenbarte Fräsinstrumentarium beseitigt die Mängel der bekannten Systeme, indem eine Fräsführung nach Anspruch 1 bereitgestellt wird, die zur Aufnahme einer Fräsvorrichtung mit dem Femur verbunden wird. Das Fräsinstrumentarium weist eine Ausrichtführung auf, die vom Chirurgen verwendet wird, um eine Femoralklammer oder -basis auf die medialen oder lateralen Seiten des freiliegenden Femurs an seinem distalen Ende zu setzen. Wenn die Klammern gesetzt sind, wird die Ausrichtführung entfernt und eine Fräsführung wird mit den Basen verbunden. Die Fräsführung richtet eine Serie von Referenzebenen mit jeweils einem Schlitz ein. Eine kraftbetriebene Fräsvorrichtung, mit der ein Schneidkopf verbunden ist, wird von den Schlitzen entlang der Referenzebenen geführt, um einen Abschnitt des Knochens genau abzufräsen. Der Abstand zwischen der Fräsvorrichtung und dem distalen Ende des Schneidkopfs ist relativ kurz, und der Schaft des Schneidkopfs ist steif, um jegliche Durchbiegung des Schneidkopfs dadurch zu vermeiden. Ferner weist die Fräsvorrichtung eine spulenförmige Spitze auf, die mit den Schlitzen formschlüssig in Eingriff tritt, um sicherzustellen, daß die Fräsvorrichtung im wesentlichen senkrecht zu den Referenzebenen der Fräsführung gehalten wird. Eine derartige Steuerung der Fräsvorrichtung stellt eine extrem glatt gefräste Oberfläche zur Aufnahme des Implantats sicher. Bei Bedarf kann weiteres Instrumentarium mit den Femoralbasen verbunden werden, die einen gemeinsamen Verbindungspunkt für die zusätzlichen Instrumente bilden würden, wobei die Ausrichtung zwischen den verschiedenen Instrumenten sichergestellt wird.The revealed milling instruments eliminates the defects of the known systems by providing a milling guide according to claim 1 which is used to hold a milling device connected to the femur. The milling instrument has an alignment guide, used by the surgeon to create a femoral brace or base on the medial or lateral sides of the exposed femur to put on its distal end. When the brackets are set, becomes the alignment guide removed and a milling guide is connected to the bases. The milling guide straightens a series of reference planes, each with a slot. A powered milling device, with which a cutting head is connected, is from the slots along guided the reference levels, to accurately mill a section of the bone. The distance between the milling device and the distal end of the cutting head is relatively short, and the Shank of the cutting head is stiff to any deflection of the cutting head to avoid this. Furthermore, the milling device has a coil-shaped tip which engages positively with the slots to ensure that the milling held substantially perpendicular to the reference planes of the milling guide becomes. Such control of the milling device provides an extreme smooth milled surface for Recording the implant safely. If necessary, further instruments connected to the femoral bases that have a common connection point for the additional Would make instruments ensuring the alignment between the different instruments becomes.
Wenn die Femoralbasen mit dem distalen Ende des Femurs verbunden sind, kann als Wahlmöglichkeit eine einstückige Schneidführung mit den Basen verbunden werden, um die Resektion des Knochens mit einem standardisierten Pendelsägeblatt zu ermöglichen. Die Schneidführung weist mehrere Schlitze auf, so daß alle Schnitte, die für den Femur erforderlich sind, mit einer Schnittführung durchgeführt werden können, ohne die Führung neu auszurichten. Wenn alle erforderlichen Schnitte durchgeführt werden, ohne die Führung zu verschieben oder ohne zusätzliche Führungen zu erfordern, werden die Genauigkeit und die Wiederholbarkeit der Schnitte verbessert.If the femoral bases are connected to the distal end of the femur, can as an option a one-piece cutting guide be connected to the bases to resection of the bone with a standardized pendulum saw blade to enable. The cutting guide has several slits, so that all cuts for the femur are required to be performed with a cutting guide can, without the leadership to realign. When all necessary cuts are made, without the leadership to move or without additional guides to require, the accuracy and repeatability of the Improved cuts.
Ein weiterer Vorteil der Erfindung besteht darin, eine Fräsführung bereitzustellen, die zur Führung einer Fräsvorrichtung mit einem Knochen verbindbar ist, um eine Oberfläche des Knochens zur Aufnahme eines orthopädischen Implantats zu präparieren.One Another advantage of the invention is to provide a milling guide, to lead a milling is connectable with a bone to a surface of the bone for receiving a bone orthopedic To prepare implant.

Je nach Typ des Femoralimplantats, das vom Femur aufzunehmen ist, muß der Chirurg möglicherweise eine Kerbe im distalen Ende des resezierten Knochens ausbilden. Normalerweise ist dies erforderlich, um Implantate anzupassen, die als Knie mit eingeschränkter Kondyle und posterior stabilisierte Knie bezeichnet werden. In diesen Fällen funktionieren im allgemeinen die hinteren und/oder vorderen Kreuzbänder des Knies nicht einwandfrei oder sind entfernt worden, wie vom Chirurgen entschieden. Das Implantat muß daher die Funktion der Bänder ersetzen. Dazu ist es üblich, daß das Femoralimplantat einen bestimmten Typ von Vorsprung aufweist, der sich von der Tibialplatte nach oben und in das Femur erstreckt. Um ein solches Implantat aufzunehmen, muß eine Kerbe im distalen Femur ausgebildet werden.ever According to the type of femoral implant to be taken from the femur, the surgeon must possibly form a notch in the distal end of the resected bone. Usually this is required to adapt implants that as a knee with restricted Condyle and posterior stabilized knees are referred to. In these make In general, the posterior and / or anterior cruciate ligaments of the Did not knee properly or have been removed, as by the surgeon decided. The implant must therefore the function of the bands replace. It is customary for this that this Femoral implant has a certain type of projection, the extends from the tibial plate upwards and into the femur. To accommodate such an implant, a notch must be in the distal femur be formed.
